The free week will begin just before the launch of the game's first map pack, which will be released for free — like all Shadow Fall map packs — on March 4. Starting at 8 p.m. ET on March 3, all PlayStation 4 owners will be able to download a Shadow Fall multiplayer client from the PlayStation Store and play for the subsequent week.
Unlike the retail version of Shadow Fall, the multiplayer trial period will not require you to have a PlayStation Plus subscription to play. The single-player campaign won't be playable during the trial unless you already own the game.
During the week, Guerrilla will offer special Warzones for the new downloadable maps, as well as global leaderboards for the Capture and Team Deathmatch modes. Members of in-game clans, a feature that debuted in Shadow Fall with the version 1.09 patch earlier this month, will be able to partake in challenges and win prizes.
